- the gap flows through between the second and the third cylinder of a heat transfer medium becomes.
- a heat carrier medium for example, ammonia is used here. Due to the small filling material of such scraper heat exchanger and the small layer thickness of cooling food preparation, the passage speed can be comparatively be chosen large, resulting in short residence times of the food preparation in the Scraper heat exchangers result. Due to the continuous process is a vacuum cooling not possible in connection with scraper heat exchangers. As a disadvantage in continuous Procedures, it should be further considered that the change between different Product types due to the required complicated cleaning processes is not readily possible, so that an economical production of smaller quantities not possible.
- the invention is based on the object, a batch process for cooling and Mixing a flowable food preparation to create, despite the batch production achieve high production volumes per unit time in an economical way to let. Furthermore, with the invention, an apparatus for carrying out the inventive Be provided method.
- this object is achieved according to the invention achieved in that uses a compression refrigerant as the heat transfer medium that is within the space of the heat jacket at least in part of the liquid goes into the gaseous phase.
- the effect of increasing the viscosity becomes avoided even with greater lowering of the temperature.
- the compression refrigerant evaporates at least in part during its course through the double jacket and thus partially passes into the gaseous phase. Because of this phase transition required evaporation ebb can be a large amount of heat to the boiler to be cooled be withdrawn. With the help of the method according to the invention can thus be realize very high heat transfer coefficients in the double mantle, so that the Cooling times can be significantly reduced.
- a drastic reduction of the needed Time that is, a drastic increase in the achievable temperature gradient occurs especially in the temperature range of below 40 ° C.
- the filling temperature can thus significantly be achieved faster, which is why the economy of the method according to the invention is excellent.

- propane R290
- ammonia R717)
- CO 2 R744
- refrigerants R600A or R170 R600A or R170.
- the effect of increasing the cooling rate is particularly great when the vacuum during a period of time is created by the temperature of the food still above about 30 ° C, preferably above about 40 ° C.
- the invention further ausgestaltetend is provided that the cooling device, a heat exchanger is, which is traversed by a second compression refrigerant, which in a second refrigerant circuit is performed and with the first compression refrigerant in Heat exchange stands.
- a heat exchanger is, which is traversed by a second compression refrigerant, which in a second refrigerant circuit is performed and with the first compression refrigerant in Heat exchange stands.
- the underlying object is based of a device of the type mentioned solved in that the gap in the double jacket with a pressure of at least 10 bar can be acted upon.
- the invention Method that is to realize the use of a compression refrigerant. Even if the pressure at the operating point of the device only at usually few bar (with ammonia at a temperature of - 17 ° C at around 2 bar), the in the compression chamber located in the intermediate space of the double jacket in particular at Downtimes in the summer up to room temperature or even over heated. In the event of ammonia in this case has a pressure of about 17 bar, which is the double jacket must withstand by providing a suitably solid construction.
- the device of the invention is thus characterized by the fact that not only with her Cooling soles are usable, but also compression refrigerants, where in the double jacket a phase change occurs. Due to the low temperatures associated with such Compression refrigerants can be realized with barely increasing viscosity, the Heat transfer coefficients and thus the necessary cooling times to reach the filling temperature compared to cooling devices of the prior art entirely reduce considerably.
- the interior the boiler can be acted upon by a vacuum.
- d. H. at temperatures between about 80 and 40 ° C the temperature gradient be further increased.
- the interior of the boiler should have an overpressure of at least 3 bar be acted upon to be able to make a sterilization of the boiler with superheated steam.
- An apparatus 1 shown in Figure 1 for discontinuous cooling and mixing a flowable fruit preparation has a cylindrical boiler 2 made of stainless steel with a dome-shaped bottom area 3. Inside the boiler 2 is a around the axis of rotation 4 arranged by means of a motor 5 rotatably drivable agitator 6, the arm-shaped Blades 7 adapted to the curved course of the opposite wall sections 8 are. There is thus a scraper effect of the stirring blades 7, which ensures that especially strongly cooled fruit preparation directly in contact with the wall portions 8 of Kessels 2 is, lifted from these and is conveyed into the interior of the boiler 2.
- a double jacket 9 which has a gap 10 limited by a heat transfer medium in the form of a compression refrigerant is conductive.
- the container 2 is closed at its top with a lid 13, in the one hand a with a valve 14 closable product inlet 15 opens. Furthermore, one penetrates Vacuum line 16 the cover 13.
- the from the interior of the boiler 2 by means of a vacuum pump 17 promoted mixture of water vapor and air is passed through a radiator 18th directed.
- a discharge line 19 In the bottom area 3 of the boiler 2 is a discharge line 19, which to buffer storage 20 leads for the cooled product.
- a separation tank 21 for the compression refrigerant goes to the underside thereof a leading to the refrigerant inflow 11 supply line 22, in the course of which a pump 23 is arranged.
- a drain line 24 connected, which is connected to the refrigerant outlet 12 to the double jacket 9.
- a mirror 25 of the liquid compression refrigerant is formed out in the separation tank 21, a mirror 25 of the liquid compression refrigerant is formed out. Above the mirror, on the one hand, a line 26 goes out, which via a compressor 27 and a radiator 28 is guided to a throttle 29, which via a line 30 to the separating vessel 21 is connected.
- the empty vessel 2 is a hot fruit preparation with a Temperature of about 80 to 90 ° C fed until a level up to a mirror 31 established.
- the fruit preparation is constantly in motion by rotation of the agitator 6 held.
- the compression refrigerant in the form of liquid ammonia directed.
- the one with a temperature of about minus 17 ° in the range of the refrigerant inflow 11 evaporates into the gap 10 of the double mantle 9 entering ammonia partly due to the product to be cooled.
- the cooling device formed by the device 1 operates in the manner of a flooded heater, wherein the proportion of gaseous ammonia upon exiting the refrigerant effluent 12 is about 30 percent by mass.
- the ammonia enters the separation tank 21 takes place a separation of the liquid and the gaseous phase: While the liquid Phase on the supply line 22 and the pump 23 again the gap 10 of the double mantle 9 is supplied, the gaseous fraction is compressed by means of the compressor 27, wherein its temperature increases to about 100 ° C. After a re-cooling in the cooler 28 to about 45 ° C takes place after the throttle 29, an expansion of the ammonia, which then in partially liquid form is fed to the separation tank 21.
- the speed of the motor 5 is chosen so that in the period between the sweeping two consecutive stirring blades 7 a thin Ice layer can form, which is lifted by the stirring blades 7 and into the interior of the container 2 is transported.
- the Schmelzentalpie can thus in the interior of the container for cooling the Fruit preparation can be used.
- the content of the boiler 2 is discharged by opening the corresponding valves 32 in one of the buffer tank 20.
- the capacity of the container 2 is about 1700 kg of a fruit preparation.
- Figure 2 shows the course of two Abkühlkurven a fruit preparation - each without application the vacuum cooling -, once using the inventive Method (curve A) and on the other in a cooling method according to the prior art (Curve B) using a cooling sole as a heat transfer medium in the space 10 of the double mantle 9.
- the batch quantity of the non-particulate used as a test Fruit preparation was 300 kg.
- the cooling takes place in the inventive Method (curve A) with a very large temperature gradient, so that already After about 20 minutes, a temperature of 40 ° C and after about another 15 minutes, a temperature of 20 ° C can be achieved. Even a cooling to a temperature of 10 ° C is possible in less than 50 minutes.
- the cooling of the same fruit preparation is in use a conventional cooling sole made of propylene glycol instead of ammonia as in the invention from the beginning with a smaller temperature gradient. While the At first, differences may not be too important - a temperature of 40 ° C can be reached after about 50 minutes - the temperature curve runs in particular in Area below 40 ° C extremely flat. While a temperature of 20 ° C only after approx. 165 minutes can be reached, another cooling down to 10 ° C would be another take a very long time. Especially in the area of low temperatures, where A support by a vacuum cooling is not meaningfully possible, can thus be achieve enormous time advantages with the method according to the invention.
